Title: Jaw-arm for machine welding plastic bags - using spring to keep arm in contact with driving cam
IPC: B29C65/18
Filed: 1974-06-04
Abstract: Device for controlling an element with an oscillating motion, esp. a welding clamp-jaw consisting of a frame carrying a pivot bearing for an arm (I) actuated by a rotating cam driven by a motor, the other end of the arm carrying the jaw. The novelty is that a second arm (II), also located on a pivot, is mounted on the opposite side of the cam to arm (I) and the ends of the two arms remote from their pivot mountings are connected by an elastic element. Arm (I) pref. carries a roller held onto the cam by the elastic element, which is pref. a coil spring. Used for example in the welding of plastic foils to mfr. plastic bags. Ensures that the jaw-arm is always in contact with the surface of the cam and permits high operating speed.

Title: In-line mixer for fluid transfer system - with bifurcated or trifurcated transfer-line
IPC: G01N1/38
Filed: 1974-10-11
Abstract: In a transfer-line, in which >=2 partially mixed fluids are flowing, further mixing is achieved by splitting the line into 2 or 3 separate tubes and then reuniting them. The mixing effect results from the turbulence and the changes in velocity and pressure taking place at the points of division and reunion. The tubes into which the fluid mixt. is divided may have equal or unequal lengths and cross-sections and two or more such bifurcated or trifurcated sections may be placed in series. Mixing time is reduced, and the need for a separate mixing vessel is eliminated. The system is useful for mixing blood samples or chemicals with diluents or reagents.

Patent FR-2254888-A1 (FR)
Title: Sealed container for accumulator - has single jointing and insulating sleeve extending into projecting rim
IPC: H01M50/147
Filed: 1974-11-28
Abstract: The container (1) has a U-section upper rim (2). The insulating sleeve (3) is moulded so that it has the same profile as the wall of the container; it acts as a linear inside the container and fits into the projection. The edge of the circular top plate (4) of the battery fits into the projection of the container. Sealing is effected by crimping around the projection. The insulating sleeve can be coated with an elastic material such as bitumen. This forms a sealed unit that prevents the passage of gas or liquids. In this unit, the sleeve provides both internal insulation and the crimping seal although the crimping force is absorbed by the container itself.

Title: Rotary two-stroke internal combustion engine - is suitable for use with any grade of fuel
Inventor: JEAN BERNARD ALBERT ANDRE
IPC: F01C1/063
Filed: 1975-05-30
Abstract: The rotary engine has a cylindrical outer casing (2) supporting a concentric inner casing by a single radial rib. The inner casing has five pistons (4 to 8) forming sectors of a cylinder. Each cylinder has a pin engaging a block which slides in a radial slot (11) in the crankshaft (3). The crankshaft (3) rotates in a bearing eccentric to the casing (2). As the crankshaft (3) rotates, the space between consecutive pistons alternately increases and decreases from a minimum at top dead centre to a maximum at bottom dead centre. This motion allows air to be drawn into the corner casing, then compressed and expanded to carry out the two stroke cycle.
